Dear Aldona, My colleague China Shelton and I have written two articles about building flotation systems that recycle water using a hand-pump. We've included part lists, measurements, and many photos. https://www.academia.edu/388894/The_Hand-Pump_Flotation_System_A_New_Method_for_Archaeobotanical_Recovery https://www.academia.edu/1077786/Recovering_Macrobotanical_Remains_Current_Methods_and_Techniques I hope these might help you!
